Abstract

Acquiring the phase information could significantly enhance the potential of compressed ultrafast photography (CUP) for frontier scientific exploration as well as engineering application. In this paper, we present a novel compressed ultrafast onaxis holographic imaging system that combines compressed ultrafast photography and on-axis holography techniques, to achieve phase measurements in ultrafast temporal resolution. For data acquisition, the laser passes through the dynamic scene to form the object light, and then converges with the reference light to produce a hologram. This hologram is recorded in a compressed snapshot using spatial encoding, temporal shearing and spatio-temporal integration techniques. For image reconstruction, we propose an algorithm combining the plug-and-play generalized alternating projection (PnP-GAP) and FFDNet deep denoising prior. Simulation results validate the effectiveness of our proposed method.
